Ok, attached is the output of dmseg so you can see what kind of
hhardware I run. Below is th results of zsh's process monitoring and
"time".
hw.ata.wc=3D1
"tar zxvf linux-2.4.4.tar.gz":
33.62s real, 8.12s user, 10.98s sys (56% CPU)
hw.ata.wc=3D0
"tar zxvf linux-2.4.4.tar.gz":
148.93s real, 7.41s user, 10.10s sys (11% CPU)
During the test I was playing Staind_Dysfunction_03_Me.mp3 via mpg123.
While hw.ata.wc=3D1 was enabled I could actually listen to the song. With
hw.ata.wc=3D0 it was realy choppy and would just stop at times. Any other
info you guys want??
Erick
